Quadrilateral subdivision schemes come in primal and dual varieties, splitting faces or respectively vertices. The scheme of Catmull-Clark is an example of the former, while the Doo-Sabin scheme exemplifies the latter. In this paper we consider the construction of an increasing sequence of alternating primal/dual quadrilateral subdivision schemes based on a simple averaging approach. Beginning ...

In this article, we deal with the efficient computation of Wright function in cases interest for expression solutions some fractional differential equations. The proposed algorithm is based on inversion Laplace transform a particular which discuss detail error analysis. We also present code package that implements here different programming languages. analysis and implementation are accompanied...

For a k-connected matroid M , Clark and Whittle showed there is a tree that displays, up to a natural equivalence, all non-trivial k-separations of M . In this paper, we present an algorithm for constructing such a tree, and prove that, provided the rank of any subset of E(M) can be found in constant time, the algorithm runs in polynomial time in |E(M)|.

background and objective: brucellosis is a main transmittable zoonotic disease, which is endemic, and a common health burden in iran. adenosine deaminase (ada) is an essential enzyme which is involved in purine metabolism and its role in immune system is very important. the aim of this study was to determine serum changes of ada and c-reactive protein (crp) levels in patients with brucellosis. ...

It is a pleasure to join in this tribute to a great surgeon and teacher, Samuel Clark Harvey. Though not one of his official family, and with no claim of recognition as one of his pupils and associates, nevertheless I share with many others affection as well as admiration for this fine gentleman. Dr. Harvey's research contributions began when he was a medical student at Yale. It was probably be...

As more horticultural producers in the United States transition to organic production practices, they are challenged in finding consistent and economically viable sources of suitable potting media. Commercial, peat-based media approved for certified organic production are available and custom peat-based mixes that use certified organic fertilizers could also be used. Both of these options, howe...
